Continued Access Study VIG Anastomotic Connector

Inclusion Criteria: 1. Subject is ≥ 18 years of age. 2. Subject requires the creation of a vascular access graft for hemodialysis, secondary to a diagnosis of End Stage Renal Disease. 3. Subject has the vascular access graft placed in an upper extremity. 4. Baseline imaging shows suitable vascular anatomy/ vessel size for the InterGraft™ Venous Connector and an artery at least 3.5 mm in diameter that is suitable for creating the arterial anastomosis. 5. Subject has a reasonable expectation of remaining on hemodialysis for at least 6 months. 6. Subject or his/her legal guardian understands the study and is willing and able to comply with the dialysis schedule and follow-up requirements. 7. Subject or his/her legal guardian provides written informed consent. NOTE: In accordance with the requirements of some Institutional Review Boards (IRBs), where applicable, only those subjects with capacity to consent for themselves will be included. Thus, where required by the IRB, adult individuals who lack capacity to consent for themselves will be excluded from the study. 8. Physician's examination at time of surgery shows no significant vessel lesions, calcification(s), anatomic structures, or abnormalities that may limit ability to safely deploy the InterGraft™ Venous Connector or create a sutured arterial anastomosis. Exclusion Criteria: 1. Subject has a documented and unsuccessfully treated ipsilateral central venous stenosis as determined by imaging. 2. Subject currently has a known or suspected bacterial, fungal, or HIV infection. NOTE: Subjects with hepatitis B or C may be included in the study. 3. Subject has a known hypercoagulable or bleeding disorder or requires treatment with warfarin or heparin. NOTE: The intent of this criterion is to exclude patients with high risk for bleeding or clotting complications. Patients who are taking the oral anticoagulant Eliquis® (apixaban) may be included in the study if Eliquis is temporarily discontinued prior to the study procedure, in accordance with the approved prescribing instructions. Patients may receive anticoagulation therapy any time after the study AV graft implant procedure, at their physician's discretion. This should be driven by an indication unrelated to the vascular access. 4. Subject has had a previous instance of Heparin Induced Thrombocytopenia type 2 (HIT-2) or has known sensitivity to heparin. 5. Subject has co-morbid conditions that may limit their ability to comply with study and follow-up requirements. 6. Subject has had \>2 previous arteriovenous accesses in treatment arm. 7. Subject is currently taking Aggrenox®. 8. Subject needs or is scheduled for any major surgery within 30 days of the study procedure. 9. Subject is currently taking maintenance immunosuppressant medication such as rapamycin, mycophenolate or mycophenolic acid, prednisone (\>10 mg), cyclosporine, tacrolimus, or cyclophosphamide. 10. Life expectancy is less than 12 months. 11. Subject is pregnant. NOTE: A negative urine pregnancy test within 24 hours of the study procedure is required in all female subjects with reproductive capacity. 12. Subject is a poor compliance risk (i.e.. history of IV or oral drug abuse). 13. Subject is enrolled in another dialysis or vascular investigational study.
